hey Daniel2,

Your initial front/side thigh symptoms sound like Meralgia Parasthetica. There's plenty of information on here/ YouTube about that condition. Sitting cross legged and nerve gliding are successful management techniques.
You definitely have nerve compression issues and I agree with Lara that it's likely to be Piriformis Syndrome giving you Sciatica like symptoms. This is a soft tissue issue and I see that you've learned a chiropractor can't help you.

Consider myofascial release. This a link to Elisha Celeste. She has plenty to say about pain and how the body stores pain. And how to release it.
